Furnace installation & replacement

A new furnace, sized for your house - not guessed at.

We run a Manual J load calculation to size the furnace, then pre-measure the space before installation day so the furnace we install actually fits the house it's heating.

Why sizing matters more than the sales pitch

An oversized furnace short-cycles, wears out early, and still leaves parts of the house uneven. An undersized one runs constantly and never quite keeps up. Either way, you paid for the wrong system.

We don't size a replacement off the unit you already have or a rule of thumb. We run a Manual J heat-load calculation and pre-measure the space, so the number we quote is based on your house, not a guess that's easy to sell.

  • Pre-measurement of the space and existing ductwork
  • Ductwork testing, so the new furnace isn't fighting leaky supply lines from day one
  • measureQuick verification of the finished install, scored from live instruments
  • Upfront, written pricing before work starts
  • Financing available through Optimus and Wisetack

Our process

Our installation process

01

Load calculation

A Manual J calculation determines the actual heating load of your home, not just a swap of your old unit's rating.

02

Pre-measurement & duct check

We measure the space and the existing ductwork before installation day, so the plan accounts for what's really there.

03

Install day

The new furnace goes in on a schedule you're told up front, with the pricing you already approved.

04

measureQuick verification

The finished system is verified with measureQuick — live-instrument readings, scored — confirming it performs the way it was designed to, not just that it was installed.
